Specification of Letters Patent.

Application filed October 29, 1906. Serial No. 341,039.

To all whom it may concern:

Be it known that I, FRED LEE KIRKMAN, a citizen of the United States,residing at Glenwood, in the county of Schuyler and State of Missouri,have invented new and useful improvements in Side-Delivery Hay-Rakes, ofwhich the following is a specification.

This invention is a side-delivery hay-rake, and has for its object animproved driving mechanism for presenting the rake-teeth to the hay in avertical position and also to retract or withdraw them.

A further object is to provide a hinged supporting-frame for the rake,so that it can be raised or lowered to vary the distance be tween therake-teeth and the ground.

In the accompanying drawings, Figure 1 is a plan view of the invention.Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is avertical section on the line 3 3. Fig. 4 is a longitudinal section onthe line 4 4. Fig. 5 is a vertical section on the line 5 5. Fig. 6 isFig. 7 is a detail.

Referring specifically to the drawings, 10 denotes the axle of themachine, on which are loosely mounted wheels 11, with a pawlandratchetconnection 12 between the hub of each Wheel and the axle, so that theaxle will be driven in the advance movement of the machine, but willremain stationary when the machine is backed, all in the Well-knownmanner.

The rake-frame 13 is arranged diagonally to the line of draft, as isusual in this type of machines, and is rectangular in shape. The frontend of the frame is supported on the axle 10 by a beam 14, extendingfrom the frame and mounted on the axle, and the corner of the framenearest the axle carries a bearing 15, through which the axle extends.

The rear end of the frame is supported by a caster-wheel 16. Above theaxle is a transverse beam 17, which is supported at its ends on thecorner of the frame 13 and the front end of the beam 14, respectively.The seat 18 of the machine is secured to the beam 17, and thedraft-tongue 19 is also attached to said beam. On the front and rearends of the frame 13 are standards 20 and 21, respectively, to which abeam 22 is fastened. The front end of said beam extends downwardly andis fastened to the beam 17. The stem 23 of the caster-wheel is swiveledin a bracket 24 on the standard 20.

To the front end of the frame 13, on the under side thereof, is hinged,as at 25, a frame 26, the end pieces of which carry bearin s 27, inwhich a rake-shaft 28 is journa ed. The rear end of the frame 26 issupported in stirrups 29, extending downwardly from the frame 13 on eachside. On each side of the frame 13 are hand-levers 30, con nected bylinks 31 with the frame 26 for raising and lowering the same. Thehand-levers are fulcrumed on brackets 32, seemed to the frame 13, andthe usual latches and segmentracks for holding the levers in adjustedposition are provided.

, To the shaft 28 is keyed or otherwise made fast at one end a spider33, and at the opposite end is fastened a disk 34. Rock-shafts 35, towhich the rake-teeth 36 are connected, are journaled in the spider anddisk. The teeth are coiled around the rock-shafts and made fast theretoby extending their inner ends through transverse openings 37 in saidshafts. The guards or fenders for the rake are curved rods 38, connectedat one end to the front bar of the frame 13 and at the other end to therear bar of the frame 26. The rods extend loosely through the front bar,so that the frame 26 may be raised or lowered.

The rake-shaft 28 is driven b y a beveled pinion 39, made fast on oneend thereof and meshing with a gear 40 on the axle 10. The gear 40 isloose on the axle and is thrown into action by a suitable clutch device4]., slidable on the axle, and operated by a handlever 42, fulcrumed ona bracket 43, extending from the beam 17. The hand-lever is providedwith the latch and segment-rack for holding it in adjusted position, andit is close to the seat 18, so that the rake can be readily thrown intoor out of operation.

The ends of the rock-shaft 35 adjacent the disk 34 have lateral bends44, forming cranks 45, at the outer ends of which are mountedfriction-rollers 46. The disk 34 carries projecting stop-pins 47,against which the cranks are pressed by springs 48, secured to said diskand bearing on the cranks. The cranks and rollers extend into acam-housing comprising a disk 49, made fast to the end piece of theframe 26 and having a peripheral flange 50, against which the disk 34abuts, thus serving to exclude dirt, hay, &c., from the housing. Theshaft '28 extends loosely through an opening in the disk 49. Insidethehousing are cam-shaped tracks 51 and 52,

on which the rollers 46 travel, and which are for the purpose ofthrowing the rake-teeth into vertical position for service by turningthe rock-shafts 35 on their axes, and thus causing the teeth to advanceand project below and beyond the guards 37 into active position duringthe lower part of the revolution and to retract or withdraw them Withinthe guards 37 during the upper part thereof. In other words, the teethrevolve with the shaft 28 and are also oscillated by means of therock-shaft, so as to be presented to the hay in substantially verticalposition and to clear themselves therefrom as they. withdraw within theguards.

In operation the rake is rotated as already described, and beingdisposed at an angle to the line of draft the hay will be delivered inwindrows on one side of the machine. The distance between the rake teethand the ground is readily regulated by raising or lowering the frame 26.

I claim 1. In a side-delivery hay-rake, a wheeled main frame, stirrupsextending therefrom, a rake-supporting frame hinged at one end to themain frame and extending at the other end into the stirrups, and meansfor raising and lowering the rake-supporting frame.

2. In a side-delivery hay-rake, a wheeldriven shaft, a frame mounted onthe shaft and carrying stop-pins, rock-shafts journaled in the frame,and having cranks at one end spring-pressed against the stop-pins,raketeeth on the rock-shafts, and a cam engageable by the cranks foractuating the rock shafts.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRED LEE KIRKMAN.
